Asuper slow snail can travel 2.2cm in one minute. how far (in pm) can it travel in 24 hours? round to appropriate number of significant figures, and show required steps used to reach your answer.

Answer : The distance covered by slow snail in 24 hours is

Explanation :

As we are given that the a slow snail can travel 2.2 cm in 1 minute. Now we have to calculate the distance covered by slow snail in 24 hours.

First we have to convert 24 hours in minutes.

Conversion used : (1 hour = 60 minutes)

As, 1 hour = 60 minutes

So, 24 hour = 24 × 60 minutes

                    = 1440 minutes

Now we have to calculate the distance covered by slow snail in 24 hours.

In 1 minute, the distance covered by slow snail = 2.2 cm

In 1440 minute, the distance covered by slow snail = 1440 × 2.2 cm

                                                                                     = 3168 cm

                                                                                     =

Now we have to convert 'cm' into 'pm'.

Conversion used :

As,

So,  

Therefore, the distance covered by slow snail in 24 hours is

6.4 cm (max) - 25 cm (min)

it is the most commonly accepted one
